The results indicated that the treatment of irradiation restrained the growth and differentiation of protocorm, especially to roots.The LD50 is 67.23Gy, because the protocorm is a integrate embryoids and higher tolerance was found. Ploidy analysis showed that most of aberrant seedlings go with the change of DNA and they were not euploid. When the plants trearted by irradiation, some of aberrant seedlings appeared stem forfication, and leaves appeared chlorophyll-deficient or green-white.,probably due to some genes' expression or closing.

結果表明：輻照處理對種胚原球莖的生長和分化有抑制作用，尤其是對根的抑制更為明顯；由于種胚原球莖的完整性好，耐受性強，其輻照半致死劑量(LD50)為67.23Gy手机看片1024精品国产；流式細胞分析表明，大多數外部形態(tài)發(fā)生改變的植株其細胞內DNA的倍性發(fā)生了改變日韩欧美入口三，出現相當多的非整倍體久久r热这里有精品视频；此外，輻照產生的變異苗出現莖分叉欧美AAAA在线视频播放、葉片缺綠或白綠相間等現象国产交换配乱婬视性色aV，可能是由于某些基因的表達與關閉引起的。
